6 Claims.

This invention relates to safety razors, and it is an object and purpose of the present invention to produce a construction of safety razor of a very simple and practical form and one which can be made economically and in which the razor blade is held firmly in position when the razor is in use but can be instantly removed when desiredfor cleaning or replacement. The invention consists of a novel structure for obtaining the objects stated, as well as many others not specifically enumerated at this time, but which will appear as an understanding of the invention is had from the following description, taken in connection with the accompanying drawing, in which: I I

Fig. 1' 'is a perspective view of one form of structure embodying my invention.

Fig. 2 is a partial side'elevation and vertical section through the razor I.-

Fig.3 is a fragmentary vertical section of the upper part of the razor, the plane of the section being at right angles to that shown in Fig. 2.

Fig. 4 is a vertical section through a modified form ofstructure of razor in which operation of the parts is reversed, and,

Fig. 5 is a plan view of the structure shown in Fig. 4. 1

Like reference characters refer to like parts in the difierent figures of the drawing.

The handle of the razor is provided by a length of tubing I which may be knurled or otherwise roughened at its outer side, the lower end of which is exteriorly threaded and equipped with a screw-threaded cap 2. In the upper end of the tubular handle I a cylindrical body 3 is mounted for vertical movement, having a reduced upper extension 4, at the upper end 01 which is a head 5 of rectangular form and of usual construction upon which a razor blade 6 may be placed. The body 3 has a vertical slot 1 therein through which a pin 8 passes, the ends of the pin extending through and beyond the sides of the tubular handle I. A rod 9 is connected to or is integral with the body 3, extends lengthwise of and within the handle I and passes freely through an opening in the cap 2. A coiled compression spring I0 is located around the rod 9 within the handle, bearing at its opposite ends against the inner side of the body 3 and the up- 50 per side of the bottom of the cap 2, the effect of which is normally to move the body 3 and the head 5 in an upward direction. A knurled knob II is fastened at the lower end of the rod 9 below the cap 2.

55 A covering and blade clamping member I2 of a shape at its lower side to fit against the upper side of the blade 6 is mounted upon two arms I3 at its ends, which arms extend downwardly and are bent in toward the handle I terminating in vertical sections which lie against opposite sides of the handle, the ends of the pin 8 passing therethrough and being riveted over to provide a pivotal mounting for the part I2.

By grasping the handle I in one hand and pulling upon the knob II with the other, the spring Ill may be compressed and the head 5 drawn downwardly, permitting a placing of a razor blade 6 thereover and then by release of the head at II, spring Ill will move the blade upwardly to press snugly against the underside of the member I2. Preferably there will be a cooperating projection 5a on the head 5 to enter a suitable notch in the under side of the member I2, locking the parts together as shown in Fig. 3. In such position the razor is operative and may be used in the usual manner. At the end of a shaving operation the head 5 supporting the blade 6 is drawn downwardly in the manner described and the member I2 ,may be turned about the axis of the pin 8 to the dotted line position shown in Fig. 1. The blade is readily removed and the parts of the razor may be very quickly and easily cleaned. The member I2 may be returned to its upper position and releasably locked in such position by the engagement of the projection 5a in the recess thereof.

In Fig. 4 the head 5 over which the blade 6 is placed is rigidly secured at the upper end of the handle member I4, the lower portion I5 of which a is of tubular form as shown. A rod I6 extends axially of the handle I4, I5, and is threaded at its lower end, onto which the shank I'I equipped at its lower end with a knob I8 is secured, compressing a spring I9 housed within the tubular portion I5 of the handle between the shank I1 and the shoulder provided at the upper end of said tubular section I5. The rod I6 at its upper end beyond the upper end of the handle member I4 is equipped with a rectangular head 20. The holding or clamping member 2I for the razor blade has a rectangular opening 22 therein slightly larger in dimensions than the head 20. With this structure afterthe member 2I has been removed the razor blade 6 may be placed upon the head 5 and the spring I9 compressed by pushing upwardly upon the knob I8, thereby elevating the head 20' to an upper position, whereupon the clamping member 2| may be placed over the head 20 in a position at right angles to that which it occupies when in use. It

After it has been placed over the head 20 by a passing of said head 20 through the opening 22, the clamping member 2| is turned to parallel the head 5 and then the pressure against the knob l8 released, whereupon the head 20 will extend across the slot 22, as shown in Fig. 5, the spring i 9 drawing the clamping member 2| snugly against the blade 6. Equivalent cooperating locking projections and recesses on the parts 5 and 2! may be used the same as shown in Fig. 3 to hold the head 5 and clamping member 2! in operative position. The release and removal of the blade 6 after a shaving operation has been performed is quick and easy, requiring merely the reversal of the operations which have been described in putting the blade in place and releasing the clamping member against it.

With this construction a safety razor is produced of few parts very simply and easily manufactured and assembled, and in which the blade may be removed for either cleaning or replacement and replaced very quickly and expeditiously.

The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.
